Tewari said: "Digvijaya Singh is a senior leader of the party and he has an opinion on several issues. We are a democratic party and everybody is entitled to their views.

"But the party and the government have made it clear that the nine-year-old Sonia-Manmohan Singh experiment has been successful.

"We have struck a fine balance in governance, incorporating inclusivity, democracy and economic growth. The diarchy has been a huge success.?

Scuttling speculation of a Rahul Gandhi versus Narendra Modi faceoff in 2014, Tewari said: "We won't be swayed by the opposition's portrayal of a particular personality.

"In 2004, we fought the elections against (prime minister Atal Bihari) Vajpayee. In 2009, we fought against (deputy prime minister LK Advani. In 2014, we will contest and win again.

"We will take our performance and our vision to the people. We will portray the Congress 'Trimurti' of Rahul, Sonia and Manmohan before the people.

"And after we win, it?s the Congress cadre and the party which will decide who will be the prime minister."

But will Rahul Gandhi continue to be a backroom player or will he shed his reluctance and lead from the front?

Tewari said: "Everybody has their own style of functioning. Rahul's work speaks for itself. As an MP and party general secretary, he has changed the party's grassroot structure. This is a revolution in its own.

"Now, he has taken over the reins of the party. Now, you will see his aggression in the next six months."
